We broke the news to you yesterday, but this morning Leighton Meester and Adam Brody gave the world the picture proof it needed that she and her O.C. starring boyfriend are indeed grinding their lovey parts!

Aww! The morning after never looked so cute!

Adam crept into his car in hangover-hiding sunglasses, while Leighton's sweetly confused smile has us wondering if these two spent sooooo many lustful hours in bed last night that they can't even remember their names!

At least we HOPE that's why they look so disheveled!

The 33-year-old actor and his 26-year-old Gossip Girl alum are both bright, charming, and ridiculously good-looking!

"My metabolism actually changed like crazy this year. I have Hashimoto's disease. It's a thyroid disease, and it's now been two years since taking the medication for it, so for the VS show I didn't want to lose any more weight, I just want to have muscles in the right place, and if my butt can get a little perkier, then that's good."
